Saw a cow standing to be mounted? Enter when you first saw it and we’ll suggest the best time to inseminate.
Enter the time you first saw standing heat to see the best time to inseminate.
| Animal | Heat comes every | Heat lasts | Signs to watch for |
|---|---|---|---|
| Cattle | 21 days (18–24) | 12–18 hours | Stands to be mounted, mounts others, clear mucus, bellowing, restlessness, drop in milk |
| Goats | 21 days (18–24) | 24–36 hours | Tail wagging, bleating, swollen red vulva, mucus, seeks the buck |
| Sheep | 17 days (14–19) | 24–36 hours | Few outward signs; seeks the ram and stands for him. A teaser ram helps |
| Pigs | 21 days (18–24) | 48–72 hours | Swollen red vulva, pricked ears, stands still when you press on her back |
Follows the AM/PM rule widely used for cattle. Your inseminator may adjust timing for sexed semen or a synchronisation programme.
